  - FLOW MEASUREMENT AND INSTRUMENTATION - Rok 2018

  The article presents an estimation of measurement uncertainty of a liquid mass flow using the orifice plate. This subject is essential because of the widespread use of this type of flow meters. Not only the quantitative estimation but also the qualitative results of those measurements are important. To achieve these results the authors of the paper propose to use the theory of uncertainty. The article shows the analysis of the...

  Standard orifice flowmeters are widely used in the chemical and energy industry. Therefore, it is essential to know how accurate the measurements made with these instruments are. The paper presents an estimation of measurement uncertainty of a liquid mass flow using the orifice plate. The authors will present the influence of ranges of the Reynolds number on the estimated uncertainty, obtained on the basis of simulation and laboratory...

  - MEASUREMENT - Rok 2020

  The article analyses the impact of the Reynolds number on the estimated uncertainty of the mass flow rate measurement using an orifice plate. The objects of the research were two types of orifices: centric (ISA) and eccentric, with the diameter ratio β = 0.5. Studies were performed by Monte Carlo simulation and experiments for Reynolds numbers in the range 10,000 ≤ Re ≤ 20,000. The obtained results have shown that for both orifice...

• Mass transfer in Spinning Fluids Reactor — Measurement and prediction

  Publikacja

  • P. Wojewódka
  • R. Aranowski
  • C. Jungnickel

  - JOURNAL OF INDUSTRIAL AND ENGINEERING CHEMISTRY - Rok 2019

  Specific mass transfer area (a) and overall volumetric mass transfer coefficient (kLa) are mass transfer parameters commonly used in the description and comparison of various chemical reactors’ constructions. Determination of these was performed for Spinning Fluids Reactor (SFR). Sodium sulfite oxidation in the presence of cobalt ion catalyst was used for the determination of a and kLa. The a and kLa were successful predicted....

• MODEL FOR MEASUREMENT OF FLOW INSTALLATION TIME IN SDN SWITCH

  Publikacja

  • S. Kaczmarek
  • J. A. Litka

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Rok 2017

  SDN is the approach in telecommunication networks that separates control plane from data forwarding plane by specifying a single network entity as a controller that defines rules (called flows) of traffic forwarding for the switches connected to it. The time that is required for installation of these rules might be a hindrance for the overall performance of SDN network. In the paper, a model for testing and evaluating the influence...
